Hi.

2.6.18-128.2.1.el5.028stab064.4 kernel (latest stable OVZ) is immune to the exploits on the issue.

The kernel is immune due to the fact that 64.4 kernel has the bypassing "mmap_min_addr" issue fixed:
http://blog.cr0.org/2009/06/bypassing-linux-null-pointer.htm l - description of the problem

Exploits for the current issue, in their turn, need this hole to gain root access.

If your problem is solved - please, report it!
It's even more important than reporting the problem itself...
